Since 2009, the California Alternative Energy And Advanced Transportation Financing Authority (CAEATFA) has handed out more than $100 million in sales tax exemption (STE) tax relief to Tesla Motors, the main beneficiary of the state government program. Tesla’s latest application, which requested about $100 million in STE on the purchase of more than a billion dollars worth of equipment that the automaker will use to develop and build its Model 3 sedan [previous coverage here], was by far the biggest application in the program’s history and comes as the program faces record demand for tax relief. As a result of this high demand and Tesla’s historical domination of the program, CAEATFA approved just 48% of Tesla’s massive Model 3 request at its December 13 meeting, leaving more than half of its latest request unfunded.
